1. A hexagon is inscribed in a circle. If the difference between the area of the circle and the area
of the hexagon is 24 m”, use the formula for the area of a sector to approximate the radius
of the circle. Give an exact answer( doesn't have to be rationalized) and round to 2 decimals.

Answers

Answer 1

Answer:

The radius, r ≈ 6.55 m

Step-by-step explanation:

The given parameters are;

An inscribed hexagon in a circle

The area of the hexagon = Area of the circle - 24 m²

The formula for the area of the circle = π·r² = π × r²

The area of each of the six equilateral triangle in the hexagon = √3/4 × r²

Where;

r = The radius of the circle

The area of a sector of a circle in which the equilateral triangle is inscribed = 60/360×π·r² = 1/6×π·r² = 1/6 × Area of the circle

Given that the sector of the circle in which one of the six equilateral triangles of the hexagon is inscribed is 1/6 the area of the circle, the difference in area between the equilateral triangle and the sector = 24/6 = 4

Therefore, the difference in the area between the sector of the circle and the area of the equilateral triangle = 4 m²

We then write;  1/6×π·r²- √3/4 × r² = 4

r²·(1/6×π- √3/4) = 4

r² = 4/(1/6 ×π - √3/4) = 48/(2·π -3·√3)

r = √(48/(2·π -3·√3) = 6.55 m to 2 decimal places

The radius, r ≈ 6.55 m.

Julio es un joven muy emprendedor y ha iniciado un negocio de venta de audífonos y cargadores. Este mes, separa la cantidad de dinero, que ha obtenido en sus ventas, en dos partes: gastos y ganancias y se percata que están a razón de 5 es a 3. Del dinero que gasta, ⅗ lo gasta en compra de más mercadería, 10% en servicios de agua, luz e internet, el restante, S/ 150,60 lo gasta en su alimentación. ¿Cuánto ha sido su ganancia en este mes?

Answers

Answer:

Julio ha ganado 90,36 soles en este mes.

Step-by-step explanation:

Tras una lectura cuidadosa del enunciado podemos inferir que por cada 5 soles destinados al gasto hay 3 soles destinados a ganancias. En lo respectivo a los gastos, la razon del componente restante, cuyo valor es de 150,60 soles, es:

[tex]r = 1 - \frac{3}{5}-\frac{1}{10}[/tex]

[tex]r = 1 - \frac{6}{10}-\frac{1}{10}[/tex]

[tex]r = \frac{3}{10}[/tex]

En otras palabras, el componente restante corresponde al 30 % del dinero destinado a gastos. Entonces, el dinero total destinado a gastos es:

[tex]x = \frac{150,60\,soles}{0.3}[/tex]

[tex]x = 502\,soles[/tex]

Sabiendo la razón existente, es decir, 5 soles para gastos por 3 soles para ganancias, obtenemos la ganancia obtenida por Julio en este mes por la siguiente regla de tres simple:

[tex]y = 150,60\,soles \times \frac{3\,soles}{5\,soles}[/tex]

[tex]y = 90,36\,soles[/tex]

Julio ha ganado 90,36 soles en este mes.

Today, a bicycle rider rode her bike 5 1/2 miles to raise money for her school. Yesterday, she rode 6 1/4 miles her grandfather said he would give her 2$ for every mile she rode. How much money did she earn?

Answers

Answer:

.125 or 1/8

Step-by-step explanation:

The question is looking for the difference divided by the long ride. The long ride is 6 1/4 miles, so now we need to find the difference.

In order to do this, we take the larger distance and subtract the smaller distance.

We would take (Tip: Use decimals when you can. They are easier to work with ) 6.25 - 5.5 and we get .75 or 3/4 of a mile.

Now, we put .75 over 6.25 and simplify.

Find the error and explain what the correct step should be

Answers

Answer:

m = 12, the error was that the student did not divide both sides by -. so they got the incorrect answer

Step-by-step explanation:

okay, so you want to get m

because m is divided by 3, to counter it, you multiply both sides by three

-m/3 = -4

-m/3 times 3 =-4 times 3

because 1/3 times 3 =1, and -4 times 3 = -12, you get

-m = -12

then, divide both sides by - (because you want positive m)

and you get m = 12

the error was that the student did not divide by the negative, so in the end, their sign was wrong.

Step-by-step explanation:

Factor 3 into its prime factors

          3 = 3  

Note that 3 is a prime number, it only has itself as a factor (that is on top of the trivial factor "1")

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.

In our case however, all the factors are only raised to the first power and this means that the square root can not be simplified

The simplified SQRT looks like this:

if the slope of BC is 1/2 what is the slope of AC

Answers

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete.

However, I'll answer base on the following assumptions.

1. AC and BC are parallel.

2. AC and BC are perpendicular

For (1)

Parallel lines have equal slopes.

So, AC = BC = ½

For (2)

Slope of perpendicular line is:

m1 * m2 = -1

Take m1 as slope of BC

So, we have

½ * m2 = -1

Solve for m2

m2 = -1/½

m2 = -1 * 2

m2 = -2

Hence, the slope of AC is -2

which inequality is true for all real numbers? Check all that apply.
1. a-b < a+b
2. ac ≥ bc
3. if a ≥ b, then a+c ≥ b+c
4. if c > d, then a-c < a-d
5. if a < b, then a < b+c

Answers

Answer:

The answer is 1, i.e a-b < a+b

Its C: If a ≥ b, then a + c ≥ b + c

and D: If c > d, then a– c < a – d

Kevin rented a truck for one day. there was a base fee of $17.99, and there was an additional charge of 95 cents for each mile driven. Kevin had to pay $157.64 when he returned the truck. for how manny miles did he drive the truck?

Answers

Answer:

Step-by-step explanation:

Base fee = $17.99

Additional charge = $0.95 for each mile driven

If Kevin paid $157.64 when he returned the truck and we want to find out how many miles he drove the truck, step 1 would be to subtract the base fee.

157.65 - 17.99 = 139.65

This means that the remaining $139.65 is how much he paid for the miles he drove.

Since we know each mile costs $0.95.

Simply divide $139.65 by $0.95 to work out how many miles he drove.

Miles driven = 139.65 / 0.95 = ?

When looking at graphs, which of the following statements is true about functions? If each vertical line passes through only one point, it is a function. Each vertical line must pass through at least two points to be a function. If there are more than 3 points on the graph it is not a funcion. A function cannot be represented on a graph.

Answers

Answer:

If each vertical line passes through only one point, it is a function.

Step-by-step explanation:

The true statement about functions:

-If each vertical line passes through only one point, it is a function.

What is function?

"It is a relation between a set of inputs and a set of possible outputs."

What is vertical line?

"Any line parallel to the Y-axis"

What is vertical line test?"It is a method that is used to determine whether a given relation is a function or not.""This test states that, any vertical line in the plane can intersect the graph of a function at most once".

For given question,

We need to determine where the given graph represents a function or not.

When we look at graphs,

Using vertical line test,

If any vertical line intersects the graph more than once, then the graph is not a function.

Therefore, the true statement about functions:

-If each vertical line passes through only one point, it is a function.
